Transcript of Climate Change

The melting of Arctic sea ice is when sea ice in the arctic circle is decreasing due to global climate change. Temperature in the Arctic has increased at twice the rate as the rest of the globe. By the end of the century the arctic climate will have gone up 14°F. According to recent studies the arctic is melting 12% per decade- it will be ice free by 2030. This causes species endangerment, extinction, and the weakening of global ocean circulation.To understand climate change you must first understand greenhouse gasses. When the sun sends heat waves to the Earth, some of the waves are reflected back to space. Those that penetrate the atmosphere are kept there by the greenhouse gasses to heat the Earth. Humans are creating excess greenhouse gasses and as a result, we are trapping more heat in the Earth. This changes how our ecosystem works and can cause drastic damage. Climate change is also known as global warming.What is Climate Change?What is the Melting of the Arctic Sea Ice?The melting of Arctic Ice is caused by climate change. Due to climate change, animals that live in the Arctic are steadily decreasing. Some species have already become extinct or endangered. For example, polar bears rely on the ice to hibernate and animals rely on ice to have a sturdy ground to walk on. If the climate continues to rise, the animals will be thrown off of their natural yearly cycle that goes along with the sea ice freezing over.What Animals are Affected by Sea Ice Melting?Many animals are affected by the melting of the arctic sea ice. Some of the main animals that are being affected by this are polar bears, narwhals, seals, seabirds, walrus and the the related food web. Other climate-related threats include decreases in marine species and ice algae. Their extinction affects humans because the food web will be disrupted and the ecosystem will crash. If one animal dies of it will effect the entire population. This will cause decreasing in habitats and food supply.Global WarmingTHE MELTING OF THE ARCTIC SEA ICE

Every winter the arctic completely freezes over and is covered in ice sheets. This is part of the animals natural system, so these changes are effecting them drastically. HowIs This Happening?Save the Arctic!How Can We Help?We can help stop global warming and in turn save the arctic animals and stop arctic sea ice melting.

1.Choose an electric or hybrid vehicle. Over its lifetime, a hybrid car will save roughly $3,000 in fuel costs compared to a car that uses only gasoline. It will reduce the amount of greenhouse gasses used.

2. Travel in public transportation so that you are emitting less fossil fuels into the atmosphere.

4. Never pollute! This will release greenhouse gasses into our atmosphere.

5.Speak out and spread the word about global warming and try to convince people to make a stand as well. Some scientists believe that the arctic is gaining more ice than they are losing. They think this because the ozone layers temperatures have been dropping which leads to more areas of water that can be frozen. Ozone levels over Antarctica have dropped causing stratospheric cooling and increasing winds which lead to more areas of open water that can be frozen. They also believe that water is losing its salt content and will result in fresher water that will freeze over sooner. Some others believe that this is a natural occurrence and that this, like the ice age, is not due to human actions.Counter ArgumentHow does this AffectMeThis problem affects me because I am an animal lover. Knowing that one day we may have to tell younger generations of an animal called a polar bear that went extinct when we were kids, is heartbreaking. I do not want any animals to be hurt due to arctic sea ice melting. I think that we should come up with more energy efficient ways to live our lives. The animals need our help!
